PNEUMATIC rrmo PLAYER.

To all whom it may concern:

Be it knownthat I, WALTER LANE, a citizen of the United States, residing at Holland, Michigan, have invented certain new and useful Improvements in Pneumatic Piano Players, of which the following is a specification.

. This invention. relates to improvements in pneumatic piand'players;

It has to do' with improved w'eb guiding 'mea'n's'for controlling the web when the key" is varied intransposing. By varying'the position'of the roll and the web in its relation to the tracker accomplished.

.My invention applies the principles of web guiding ex amplified in United States Letters Patent No. 789,053, of MayQ, 1905,

to J..OConnor, and similar structures, to a transposing (lei/109.;

The main object of the invention is to provide an effective tran's'pos'ing device in which the web guiding feature is maintained and in which the loud pedal operating means is also effectively utilized;

Further objects, and objects relating to" details and economies of construction and operation will "appear from the detailed description toffollow." j

I accomplish theobjects of my invention by the devices and'means. described in the following specification. The invention is clearly definedin the claims.

A structure constituting a preferred embodiment of my invention is illustrated in the accompanying drawing, forming a part of this specification, in which:

Fig. I is a front view of my transposing mechanism with the music roll shown in position on the tracker bar by dotted lines,

' showing also the slides that carry the tube to the loud pedal'a'nd also the tubes to the web guiding devices.

Fig. II is a front view similar to that of Fig. I, with the music roll shifted to another position in transposing, showing also how slides are shifted in transposing.

Fig. III is an enlarged section of the tracker bar with my improved slide showing the opening for the tube to the loud pedal and also the opening of the tubes to the web guiding devices.

4 transposin bar such 'tran's'posing is corresponding to line 77 of Figs. I and II,

' drawing.

Specification of Letters Patent. 7 Patented J ly 11, 1922 A lication filed May '19, 1211?. Serial No. 169,669.

'position -a's in said Fig. II. 1

Fig. is a sectional view taken on a line corresponding to line 6-6, of Figs. I and II,show ing wayfor slide and also connections fortune of thetubes to the tracker bar device. Fig. VI is a sectional view taken on a line showing-means for'connecting the tracker bar to the loud-pedal tube. a Fig VIII is a detail elevation view of the connection of the pitman 11 to the rock shaft arm 11'.' 1

In the drawing, similar numerals of reference refer to similar parts throughout the several views, and the sectional views are taken looking inthe direction of the little arrows at the ends of the section lines.

Referring to the reference numerals, 1 represents a support for the roll su porting frame 2. The sheet or web-supportmg rolls 3 and 3 are supported by axially adjustable spindles. The roll 3' is supported by the axially-adjustable spindles 4 and 7, and the roll 3 is supported by the spindles 4 and 7, the spindles 7 and 7 being drivin spindles. The spindle 4 is urged against tie roll by the spring 5. The sprin 5' urges the spindle 4 normally to the rig t as shown in the he spindles 7 and 7 are journalled in frame members 8, the frame members 6 and 8 being connected by rods 9 at top and bottom; Details of the means for shifting this spindle carrying frame are not illus trated. I

I provide a double pneumatic 12 for actuating the upper roll 3 independently of the shifting of the frame. This double pneumatic 12 is connected by the link 11 to the rock shaft arm 11' on rock shaft 10. On the opposite end of this rock shaft is a cam 10 acting upon the spindle 7 to force it axially against the tension of the spring 5', the spring 5 returnin it in the opposite direction when the shifting of the cam permits.

25 embodied the same.

The double pneumatic 12 is controlled from trackuslide or oohtrol nien her 133 and 1G nioiui ed on the {inner frrime rrleiri ers' 6 and 8 in reacting relation to the tracker bar 17. The tracker slide or control members have ducts 14 and 18; the'diicts beingc'onnected to the pneumatic 12 lo y th e 1 5. The tracker slide or control mam r'lB is also preferably provided with duct 19 c0niidted to =the loud pedal -pneui'na'tic.
